AJAX：异步请求不返回布尔值

Question

我试图返回true或false，具体取决于用户令牌和＆amp;在本地存储中的作用是可以的。出于某种原因，我作为回应得到了不确定......你们能帮助我吗？

  function isLogged(roleNeeded) {
    var token = "asd";//localStorage.getItem("token");

      function handleResponse(data){
          ajaxresponse = data;

          var val;
          var localRole = "s";//localStorage.getItem("role");

          val = (data.status === "ok" && localRole === roleNeeded);
          return val;
      }
      loadAjax(token, handleResponse)
  }
  function loadAjax(token, handleResponse) {
      $.ajax({
          url: 'http://localhost/users/login/verify',
          method: 'GET',
          headers: {token: token},
          success: function(data)
          {
            handleResponse(data)
          }
      });
  }
